Killary Harbour

The flooded valley is 16 kilometres (9.9 mi) long, and in the centre over 42–45 metres (138–148 ft) deep; the sea level is higher outside its mouth, as is normal for a fjord.[2] For nearly half its length, it runs south east from the Atlantic, and then it crooks and runs directly east. It narrows after the infall of the Bundorragha River, and then widens in the vicinity of Leenane. In its innermost section, it becomes very narrow, widens where a small river comes in from the south, and ends with the line of the valley of the River Erriff. The river itself does not enter on the main line of the Harbour but curves northwards and then runs south into the inlet.

The northern shore rises sharply to a much greater extent than the southern, which is in places merely hilly. On that northern shore lies the mountain Mweelrea, Connacht's highest, rising to 814 metres (2,670 ft), and the sides of which fall steeply into the inlet, with Uggool Beach at its western edge. To the south rise the Maumturk Mountains and the Twelve Bens. The island of Inishbarna is situated at the mouth of Killary Harbour.[3] The area contains some of Ireland's most dramatic scenery.

The Harbour is a sheltered waterway, and otter are sometimes found. Both grey and harbour seals,[11] and dolphins, and sharks,[12] can be sighted, and on at least one occasion there was a bearded seal sighting.[13] Salmon and sea trout are also encountered, and provide food for the seals. Some bird species frequenting the area include mallard duck and other breeds of duck, grey heron, barnacle goose, mute swan and whooper swan, and plover.

There are today two minor settlements nearby. On the southern side near the mouth of the Harbour lies the hamlet of Rosroe, between Killary and Little Killary, while the village of Leenaun (Leenane) lies two thirds of the length of the valley inland to the east. Leenaun has a hotel and guesthouses and there are one more of each at Delphi, in a valley running down to Killary Harbour from the north.

Close to Rosroe there is an old building which now houses a hostel. This building was formerly a modest house which was used by Ludwig Wittgenstein, the famous philosopher, as a quiet place to write shortly after World War II. A plaque acknowledging this was unveiled by President Mary Robinson in 1993.

Near to Rosroe begins the so-called Green Road, a rough roadway running along the side of the valley back east towards Leenaun. It stretches for approximately nine kilometres and was part of the famine relief program during the 19th century. This road passes the last remnants of the hamlet of Foher, which disappeared in the period of the Great Famine.

A second "lost village" – Uggool – lay just north-east of the mouth of the inlet, above Uggool Beach.

Killary draws considerable tourist traffic and a catamaran service run by "Killary Fjord Boat Tours"[15] from April to mid-October is a notable local employer. Aquaculture is also important locally with a salmon farm based at Rosroe while mussel rafts are a common sight further to the east.[16]
